PEA-SHELLER.

SPECIFICATION forming part of Letters Patent No. 709,657, dated September 23, 1902.

Application tiled September 28, 1901. Serial No. 76,823. (No modem To a/ZZ w/towt if; may concern:

Be it known that I, Lnwls AUGUSTUS As- PINWALL, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented an Improvement in Pea-Shellers, of which the following is a specification.

My present invention is designed as animprovement upon the devices shown and described in Letters Patent granted to me September 25, 1900, No. 658,561.

The objects of my present invention-are to simplify the device, reduce the number of parts, and make more e'ftlcient the operation of the machine.

In my present invention the cylinder comprises a rubber roller and integral spiral rib within which is a cylindrical core. The ends of the cylinder are provided with journals or caps, and a rod passes through the said caps and the core, clamping the parts in position, and at the same time I provide a cam on one end of the rod and hold a pinion in place at the other end of the rod. I also provide concaves with inclined or spirally-arranged ribs, the same being of peculiar form, and I provide a shaking device operated by the rotationA of the cylinder and the cam' thereon for swinging aplate provided for the delivery of the pods. The machine also embraces improved means ior clamping the same to a table or other support, an internal spur-gear acting in connection with the `pinion for speeding up the cylinder, and details in the construction by which the parts are held between the heads or ends, all of which are hereinafter more particularly set forth.

In the drawings, Figure 1 is an elevation generally representing my improvement. Fig. 2 is an end View. Fig. 3 is a cross-section at z c of Fig. 1. Fig. 4L is a vertical section approximately on the line Qc 0c of Fig. 3, except that a portion of the lower concave has been removed. Fig. 5 is a sectional plan on the line y y of Fig. 3. Fig. 6 is an elevation, and Fig. 7 an edge view, of a yoke-bar.

l Fig. 8 is a vertical section and partial elevation oi' one head or end and the devices employed for clamping the pea-Sheller to a table or other support. Fig. 9 is an end elevation of the lower portion of said parts and at right angles to Fig. 8. Fig. 10 is a sectional plan at m' w of Fig. 8, and Fig. 1l a sectional plan at y' y' of Fig. 8.

The heads or ends o, b are preferably of cast metal, with edge flanges for stiffness, and they are each provided with a liangedl center 2, which forms bearings for the end journals or caps of the cylinder. These heads or ends are at their lower edges provided with ribs d' b2, and the head b is provided witha spanner b'. The heads are connected together by bolts 3, which bolts also serve the purpose of holding the intermediate parts to the heads. At the lower end of the spanner b' (see Figs. 8 to 11, inclusive) I provide a clamping-screw 4 and in the spanner a recessed plate 5 to receive the upper end ot' the screw, and which plate is made with a fan-tailed end passing through a vertically-arranged nlortise in the spanner b. The end of this plate 5 is to be turned over vertically to pass through the mortise, after which it is turned over horizontally and upon the end ofthe clamp-screw 4, the plate coming against thetable or means of support and forming a socket for the end of the screw, preventing the table being marked rby the screw, andthe fan-tailed end prevents the plate being accidentally separated from the spanner. On the heads I provide stops 6, and a rod 7 passes across the machine through the heads c b, and the feed-plate c is pivotally supported by this rod 7 between the heads a b, and the free edge of the plate c rests upon the stops 6. I provide an elongated U-shaped plate d, pivotally connected to the rod 7 between the heads, the horizontal portion of said plate being provided with fingers 8, that are downwardly bent. A yokebar c (see Figs. 6 and 7) is pivotally connected upon the left hand of the rod 7, (see Fig. 1,) and this yoke-bar is connected to the plate 0L by a screw 9, which screw passes through the plate and into a lug of the yoke-bar.

The cylinder comprises the rubber rollerf, with an integral spiral rib 10, the periphery of which rib is provided with concaves that are approximately of the same length. (See` Fig. 3.) The cylindrical core gis within the rubber roller, and the rod h passes through IOO ythe delivery portion of said incline.

the cylindrical core, and I provide end journals or caps t' t" of conical form, which are adapted to [it into the iianged centers 2 of the heads a b and to lit over the ends of the core g and against the ends of the rubber rollerf. (See Fig. 4.) On one end of the rod li is a cam 11, adapted to fit into the jaw of the yokebar c, (see Fig. 6,) and at the other end of the rod Zt is a pinion 12, recessed to fit over the end journal il', anda nut 13 on the end of this rod h clamps the end journals to the cylindrical core and the pinion to one end jou rnal, holding these various parts that go to make up the entire cylinder so securely that they move as one. On the head or end ZJ' are a boss and shortl shaft 14, and an internal spur-gear 15 fits thereon and is provided with an arm and handle Zt. The spurgear 15 meshes with the pinion l2, (see Fig. 2,) and by turning the handle and the internal gear the pinion 12 and the cylinder are rotated in the direction of the arrow, Fig. 3. The ratio of size of the pinion and the internal gear provides for speeding up the parts, so that with a slow revolution ot' the internal gear the pinion and cylinder may be caused to travel quite rapidly. I provide concaves Z fm, surrounding the larger portion of the cylinder. The lower end of the concave Z is provided with pivots 16, engaging the heads Ot b, and between said heads there is a pivoted bar 17, through which passes an adj Listing-screw 13, bearing upon the upper end of the concave Z, and stops 2O on the heads limit the movement of the concave in one'direction, while the said adjustingscrew limits the movement in the opposite direction. The inner surface of the concave Z is provided with inclined ribs 19, that are stepped off. (See particularly Figs. 3 and et.) The dilection ot these ribs is opposite to the direction of the spiral, as the same is presented in opposition to the ribs. The concave m is provided with spirally-arranged ribs 21 over the inner surface, that run in the same direction as the spiral rib l() of the rubber collarthat is, in opposition thereto; but the same are at a greater inclination, and they run up over onto (See Figs. 3 and 5.) This concave m is provided with openings 22 between the ribs and at spaced-apart intervals and with iianges 23 at the ends, through which one of the connecting-bolts 3 passes, said incline 'n being held between the heads by said bolt 3 and by the forward edge of the incline resting upon the other bolt 3 and by the edges of the inclines coming below lugs 24 on the inner surfaces of the heads a b.

Below the concave m and the shaker-plate d I provide a delivery-incline n of curved form, with the edges resting upon the ribs a b2 of the heads, and said edges are notched to receive lugs 25 upon the opposite 'inner surfaces of the heads ct b, so that while the delivery-incline n is supported by said ribs any movement thereof is prevented by the lugs 25.

In the operations of the pea-Sheller the pods are fed into the machine over the feed-plate c and between the same and the upper end of the concave Z. The pods pass down against the cylinder and upon the spiral rib 10, and by the rotation of the cylinder the pods are carried forward against the concave Zand its stepped inclined ribs 19, the distance .between the parts growing less as the pods approach the concave. The act-ion of the spiral rib and the ribs 19 is to roll over, twist a-ndsnap the pods open, and at the same time progress the pods slightly lengthwise of the cylinder, producing a nipping action tending to separate the peas from the pods as well as to snap the pods open. As the pods pass over the concave Zonto the concave 'm the general direction of movement is reversed, because ofthe difference of inclination of the ribs 2l on the concave m, the cylinder meanwhile traveling at considerable speed and forcing the pods over the ribs and gradually lifting the pods without the peas over the upper edge of the concave m onto the shakerplate CZ, the peas meanwhile having passed through the openings 22 in the concave m and openings between the meeting edges of the concaves Z and m, the peas falling upon the delivery-incline n and being received into any suitable receptacle. The movement imparted to the yoke-bar e by the cam l1 and therefrom to the U-shaped plate cZ is a shaking or jigging action tending to move the pods as received from the concave m upon and over the surface of the plate CZ and away, delivering the pods over the fingers 8 into a receptacle at the left-hand side of the machine. (See Fig. 3.) It' the pea-pods are small, it is advantageous to bring the concave Z nearer to the cylinder by the action of the adjusting-screw 18, which forces the upper edge of the concave nearer to the stops 20 on the heads, and in the movement of the parts should any pods be carried around with the cylinder and collie against the under surface or edge of the feed-plate c the same will lift to allow the pods to pass by and to pass a second time into the machine, as the said feed-plate c rests freely upon the stop 6.
